The rigid main body of the storage unit includes a bottom cover having a bottom surface with a recessed central region positioned between adjacent side regions that extends between top and bottom surfaces of the main body and facilitates mounting the storage unit to a tree or other mounting structure. A top cover has a lip that extends over an edge of the bottom cover and a gasket creates an airtight and watertight seal therebetween. At least one hinge couples the rigid top cover to the rigid bottom cover and an anchoring member coupled to a top surface of the main body. Accessory panels provide attachment points for storage on exterior and interior surfaces of the storage unit.

BACKGROUND OF THE INVENTION

Embodiments of the invention relate generally to storage units and, more particularly, to a portable, wearable storage unit that includes an integrated mounting system and a rugged, weatherproof design that facilitates transport.

Because a sportsman often remains in the same location for a long period of time, it is desirable to bring a storage unit to the hunting site containing items such as food, water, a phone, camera, and hunting accessories such as optics, calls, scent, and the like that will be used over the period of the stay. Traditionally a sportsman might carry the above-mentioned items to the hunting site in a soft-sided backpack that may be secured at an elevated position on a tree in situations where the sportsman is hunting from an elevated stand or positioned near or inside a blind at ground level. Locating the pack in close proximity to the sportsman allows the sportsman ready access to materials within the pack during the extended hunting event.

However, existing backpack-style storage packs pose a number of disadvantages to a sportsman. First, many of these packs hinge open from top to bottom. While this configuration may provide ready access to stored contents when the pack is opened on a horizontal, flat surface, any unsecured items located within the front cover of the pack are likely to spill down to the ground when the pack is opened in a vertical configuration. When loaded, soft-sided bags are also bulky and may interfere with the hunter's line of site from the stand. The zippered closure also is often only operable in one direction, thereby limiting the number of orientations in which the pack can be positioned on a tree. In order to access items in the pack while seated in the stand, the hunter may be forced to position the pack in a location that interferes with a desirable line of sight for hunting or twist his or her body in an awkward manner.

Existing soft-sided gear packs often are not reliably weather resistant, causing the hunter to transport the pack back and forth to the hunting site with every trip. Doing so generates undesirable noise both in carrying the pack and positioning the pack at the hunting site and, in unfortunate cases, results in dropped and lost items along the path to and from the hunting location. Operating the zippered closures of existing backpack-style storage packs to access the internal contents also generates unwanted noise while hunting.

Carrying the weight of a heavy pack and also creates sweat, which is especially disadvantageous on cold days as the hunter will quickly chill after getting settled into his or her stand. Sweat also generates scent, which increases the likelihood that the sportsman will be detected by surrounding wildlife. The odor of any food within the pack is also readily detectable to nearby wildlife as a result of the breathable fabric construction of soft-sided packs.

Therefore, it would be desirable to have a portable storage unit that addresses the above-mentioned limitations of soft-sided gear packs by providing a wearable and weather resistant configuration that can be easily transported out to a hunting site, securely mounted at the site with minimal noise, and left at the hunting site for extended periods of time. It would also be desirable for such a storage unit to be designed in manner that facilitates easy access to stored items with minimal noise generation while maintaining a broad line of sight and permits ambidextrous operation—allowing the hunter flexibility to configure the pack for either right hand or left hand operation. It would further be desirable for such a pack to be airtight in order to contain odors of stored components, allowing the hunter to leave a cache of food at a particular site without being detected by animals.

DETAILED DESCRIPTION

Embodiments of the invention are directed to rigid units or packs useable for transporting recreational, hunting, and fishing equipment. As described in detail below, the portable storage units disclosed herein are designed to be watertight and airtight and include an integrated mounting system that may be used to easily and securely attach the storage unit to a tree or other structure for temporary or long term storage. The storage unit also includes a backpack-style carry strap system to facilitate transport by foot and mounting brackets that form attachment points to enable secure transport by vehicle. External and internal mounting panels provide universal attachment points for coupling different types of accessories to external and internal surfaces of the storage unit in a variety of different configurations. Additional benefits and features are described in detail below.

FIGS. 1 and 2 are front and rear perspective views of a portable storage unit or pack 10 in accordance with one embodiment of the invention. Storage unit 10 includes an elongated enclosure or main body 12 comprising a top cover 14 and a bottom cover 16. Top cover 14 and bottom cover 16 are constructed of a rigid material. In a preferred embodiment, top cover 14 and bottom cover 16 are fiberglass. Alternatively, top cover 14 and bottom cover 16 may be formed of a plastic, polymer, or other composite material that gives main body 12 a rigid construction. An optional carry handle 18 (shown in phantom) is provided on a side surface 20 of the bottom cover 16 of main body 12. Handle 18 may be coupled to main body 12 using one or more fasteners, as shown, or molded or otherwise integrated into the profile of side surface 20 in alternative embodiments.

Top cover 14 and bottom cover 16 are connected at one side via one or more hinges 22, shown in FIG. 5. In the illustrated embodiment, hinges 22 are torque adjustable and include an adjustment fastener 24 that may be tightened or loosened depending upon the user's desired range of rotation of hinges 22. While hinges 22 are shown as being attached with a series of fasteners, in alternative embodiments hinges may be molded or cast within top and bottom covers 14, 16. In a preferred embodiment, storage unit 10 is constructed such that there is no metal-on-metal contact between moving components to minimize noise during operation. Thus, in one embodiment hinges 22 are constructed of a polymer or a having a polymer coating that minimizes noise during operation.

One or more latching mechanisms 26, 28 are provided on the side of main body 12 opposite hinges 22. While the illustrated embodiment is shown having two latching mechanisms 26, 28, alternative embodiments may include a single latching mechanism or three or more based on the overall size of the unit and various design specifications. Each latching mechanism 26, 28 includes a latch 30, 32 and corresponding receiving body 34, 36. Latches 30, 32 are attached either to the top cover 14 of main body 12 as shown, or the bottom cover 16. Similarly receiving bodies 34, 36 may be attached to the bottom cover 16 as shown, or to the top cover 14. Latches 30, 32 are releasably engageable with corresponding receiving bodies 34, 36 so that when latches 30, 32 are engaged by receiving bodies 34, 36 main body 12 is maintained in the closed or sealed position shown in FIGS. 1 and 2.

In one embodiment, latch 30 includes a toggle 38 that is pivotably attached to a mounting flange 40 coupled to top cover 14. As illustrated in FIG. 10, toggle 38 includes a body portion 42 that is received within a slot 44 formed within receiving body 34. A collar 46 formed within body portion 42 engages receiving body 34 as shown and retains toggle 38 in an extended or elongated position that maintains sufficient tension on top cover 14 to maintain main body 12 in a closed position. Toggle 38 further includes a handle portion 48 that permits a user to grasp and operate toggle 38. In the illustrated embodiment handle portion 48 is generally T-shaped, but can be formed having other shapes in alternative embodiments that facilitate operation of latching mechanism 26 by a user.

Toggle 38 is made of a flexible, stretchable material, and UV resistant such as, for example, a synthetic rubber or other elastomer that permits toggle 38 to transition between the stretched or extended position shown in FIG. 1 to an unstretched or retracted position when toggle 38 is disengaged from receiving body 34. In one embodiment receiving body 34 is made of metal or another rigid material and is coupled to bottom cover 16 of main body 12 with a plurality of fasteners. Alternatively, receiving body 34 may be molded into the outer surface 20 of bottom cover 16.

In the illustrated embodiment, latching mechanism 28 is a lockable component and, as such, differs in design from latching mechanism 26. In alternative embodiments, storage unit 10 may include a single lockable latching mechanism, multiple lockable latching mechanisms, or one or more non-locking latching mechanism similar to latching mechanism 26. Similar to latch 30, latch 32 includes a body portion 52 that pivots relative to its mounting flange 54. When latching mechanism 28 is in its closed position shown in FIG. 1, a protrusion 56 extending outward from receiving body 36 passes through a slot 58 (FIG. 10) formed through body portion 52. Latching mechanism 28 may then be locked in a closed position by inserting a padlock 59 through the opening 60 in protrusion 56.

As shown in FIG. 2 and in detail in FIGS. 4, 7, and 8, the bottom cover 16 of main body 12 includes a central portion 62 that is recessed toward the interior of main body 12 relative to adjacent side portions 64, 66 and extends across the length 68 of bottom cover 16. In one embodiment, a mounting strap 70, shown in FIG. 2, is coupled to the central portion 62 proximate a first end 72 of main body 12 to provide an attachment surface for a backpack-style carry strap system 74. A flexible clasp 76 is provided at an upper surface of carry strap 74 and extends through mounting strap 70 to couple carry strap system 74 to bottom cover 16 of main body 12. Flexible clasp 76 includes a toggle end 78 and a receiving end 80 that releasably engage one another to permit carry strap system 74 to be quickly and easily attached and removed from main body 12 as desired. Closeable latches or carabineer hooks 82 are provided at the ends of the left and right shoulder straps 84, 86 of carry strap system 74 and releasably engage with a pair of mounting points 88, 90 coupled to bottom cover 16 proximate a second end 92 of main body 12. When used with backpack strap assembly 74, storage unit 10 functions as a wearable storage unit and provides a rugged transport mechanism for sporting or hunting gear, water, food, and other stored items. For purposes of clarity, backpack-style carry strap system 74 and mounting strap 70 are omitted from FIGS. 3-8.

Referring now to FIGS. 3 and 4 and with continued reference to FIGS. 1 and 2 as appropriate, a second pair of mounting points 94, 96 are coupled to bottom cover 16 proximate the first end 72 of main body 12. Mounting points 88, 90, 94, 96 provide attachment points for clips or straps that may be used to secure storage unit 10 to a vehicle, tree, or other structure. A series of raised horizontal ribs 98 are formed within the central portion 62 of bottom cover 16 and extend outward therefrom. When storage unit 10 is mounted to a tree, these ribs 98 frictionally engage the uneven surfaces of the tree bark and aid in securing the storage unit 10 at a fixed location. As shown in FIGS. 8 and 9, ribs 98 terminate into the beveled surfaces 100, 102 that create a transition between central portion 62 and adjacent side portions 64, 66. In one embodiment surfaces 100, 102 extend outward from central portion 62 at an obtuse angle 104 to provide flexibility in attaching storage unit 10 to trees of various diameters. While it is contemplated that storage unit 10 may be constructed of various sizes and shapes for different applications, a storage unit 10 may be constructed with central portion 62 having a width 106 within a range of 3-10 inches, as one non-limiting example, to permit storage unit 10 to be mounted to trees with diameters in the range of approximately 8 inches to 24 inches.

A mounting member or anchoring member 108 is provided at the first end 72 of storage unit 10, which may be coupled to a top surface 110 of the bottom cover 16, as shown in FIGS. 1 and 2, or to the top cover 14 in alternative embodiments. In the illustrated embodiment, anchoring member 108 is a hook that includes a base portion 112 coupled to bottom cover 16 and a hooked end 114 that extends up and outward from base portion 112.

As shown in FIG. 9, mounting hook 108 is used in combination with a mounting ring 116 to secure storage unit 10 to a tree 118 or other vertical structure. In the embodiment shown, storage unit 10 is coupled to the tree 118 above a tree stand 119 to permit a hunter ready access to stored items during a hunt. Mounting ring 116 is formed having a hook 120 at one end and an eye 122 at the other end. Hook 120 is positioned over a first attachment strap 124 that is secured around the tree 118. The hooked end 114 of mounting hook 108 is inserted into eye 122 of mounting ring 116 so that the storage unit 10 hangs downward from the mounting ring 116. In the illustrated embodiment, the eye 122 is generally triangular in shape, however, eye 122 may be formed having a generally circular geometry or other shape in alternative embodiments. In an alternative embodiment, anchoring member 108 may be configured as a ring or loop coupled to main body 12. In such an embodiment, the eye portion of mounting ring 116 would be reconfigured as a hook sized to engage the ring or loop of anchoring member 108 or a threaded eye bolt, optionally rubber coated to mitigate sheen, (not shown) may be embedded into the tree 118 or other mounting structure. In yet another alternative embodiment, anchoring member 108 may be reconfigured to having a loop or other opening through which a locking cable may be threaded to hamper theft while storage unit 10 is attached to the tree 118 or other mounting structure.

After the first end 72 of storage unit 10 is secured to the tree 118 in the manner described above, the second end 92 of the storage unit 10 is secured in place against the tree 118 using a second attachment strap 126. In the illustrated embodiment, second attachment strap 126 includes clips 128 at opposing ends that attach to mounting points 88, 90. Alternatively, second attachment strap 126 may be provided having hooked ends that engage mounting points 88, 90. In one embodiment, one or both of first attachment strap 124 and second attachment strap 126 includes a ratcheting feature (not shown) that enables the length to be easily adjusted for different mounting locations. Alternatively, second attachment strap 126 is a bungee cord or other flexible strap.

Referring to FIG. 3 in particular, the top cover 14 of main body 12 is formed having a multi-faceted surface that includes a central panel 130 and a number of angled side panels 132 that extend radially outward from the central panel 130. Side surfaces 134, 136 of top cover 14 and bottom cover 16 also have a faceted geometry as shown in FIGS. 5 and 6. The exterior of top cover 14 and bottom cover 16, show in FIGS. 3 and 4 may have a textured surface finish and/or camouflage pattern to reduce glare and minimize visibility.

Referring again to FIG. 3 with reference to FIG. 1 as appropriate, in one embodiment central panel 130 includes a recessed region 138 that provides a mounting surface for an exterior accessory panel 140, which is coupled to central panel 130 via a plurality of fasteners 142. Recessed region 138 allows the outer surface 144 of exterior accessory panel 140 to be positioned co-planar or substantially co-planar with the upper surface 146 of top cover 14 of main body 12. In an alternative embodiment where central panel 130 is formed without a recess, exterior accessory panel 140 extends above the upper surface 146 of top cover 14.

As shown, exterior accessory panel 140 is formed having multiple openings 148 that are arranged in a symmetrical pattern. The openings 148 provide attachment points for various accessories, such as holsters, hooks, and accessory pouches or bags, and provide a number of different options for orienting such accessories on the exterior of storage unit 10. In one embodiment, the openings 148 are spaced and sized to facilitate attachment of Modular Lightweight Load-carrying Equipment (MOLLE)-compatible accessories, such as optional accessory 149 shown in phantom in FIG. 9. However, it is contemplated that openings 148 may be sized and spaced in any number of alternative arrangements to allow for attachment of various components. As described in detail with respect to FIG. 11, accessory panel 140 is positioned in a spaced relationship with the exterior surface 150 of central panel 130, which allows mounting straps or hooks of accessories to be looped around and woven through one or more openings 148 in exterior accessory panel 140.

A second pattern of openings 152 is formed around the perimeter of exterior accessory panel 140. An elastic or flexible cord 154 may be threaded through some or all of the openings 152 to provide quick and easy storage for clothing or other irregular shaped accessories, such as for example antlers, on the outside surface of storage unit 10. Toggle locks (not shown) may be provided at the ends of the flexible cord 154 to permit adjustments to the tension of the flexible cord 154. Openings 152 may also be used as connection points for one or more bungee cords (not shown).

Referring now to FIGS. 10 and 11, storage unit 10 is shown in an open configuration to illustrate the internal components thereof. A flexible gasket 156 surrounds the upper edge 158 of bottom cover 16. More specifically, as shown, gasket 156 covers the entirety of the top surface of upper edge 158 and extends downward to cover portions of both the exterior surface 162 and interior surface 164 of bottom cover 16. Gasket 156 is formed of a compressible material such as, but not limited to, synthetic rubber, and is coupled to bottom cover 16 with an adhesive (not shown) such as, but not limited to, silicon. When main body 12 is in its closed position (FIG. 1), with latching mechanisms 26, 28 engaged, gasket 156 abuts an interior surface 166 of a lip portion 168 of top cover 14. The tension imposed by latching mechanism 26 compresses gasket 156 between top cover 14 and bottom cover 16 and creates an airtight seal therebetween that prevents rainwater from accumulating within main body 12 and that prevents the scent of any food or other components within main body 12 from escaping the interior cavity of storage unit 10 and being detected by nearby animals. In an alternative embodiment, a similar watertight and airtight seal may be created between top cover 14 and bottom cover 16 using a compressible gasket adhered to interior surface 166 of top cover 14.

Storage unit 10 includes one or more interior accessory panels 170, 172 that may be used to organize and secure gear, food, and other accessories within the internal cavity formed within main body 12. In the illustrated embodiment, one interior accessory panel 170 is coupled to the interior surface 164 of bottom cover 16 and one interior accessory panel 172 is coupled to the interior surface 166 of top cover 14. However, it is contemplated that one or both of interior accessory panel 170, interior accessory panel 172 may be omitted, or additional accessory panels may be provided in alternative configurations.

As shown, interior accessory panel 170 is configured having a generally rectangular shape similar to exterior accessory panel 140 with a width 176 that approximates the width 106 of central portion 62 of bottom cover 16. By limiting the width 176 of interior accessory panel 170 in such a manner, two storage recesses or cavities 178 are formed on either side of interior accessory panel 170, which may be used for temporary storage of backpack-style carry strap system 74, or for storage of arrows, broken down fishing poles, firearms, or other long components. Grommets or other attachment devices (not shown) may be coupled to the interior surface 174 of bottom cover 16 to be used in combination with bungee or other cords (not shown) to retain components within storage cavities 178.

Similar to exterior accessory panel 140, interior accessory panels 170, 172 each include a pattern of openings 180, 182 that are equally sized and spaced for use in securing various accessories (not shown) within top cover 14 and bottom cover 16. The each pattern of openings 180, 182, may be formed covering substantially all of the accessory panel, as illustrated with respect to openings 180 of interior accessory panel 170, or only a portion thereof, as illustrated with respect to openings 182 of interior accessory panel 172. One or both of interior accessory panels 170, 172 may further include a second series or pattern of smaller openings 184 formed around its perimeter to provide attachment locations for one or more bungee cords (not shown) and/or a flexible cord system (not shown) similar to that shown in FIG. 1. In one embodiment interior accessory panel 170 is identical to exterior accessory panel 140 to facilitate manufacture. However, it is contemplated that the size, shape, and locations of openings 180, 182, 184 of interior accessory panels 170, 172 may differ from that illustrated in alternative embodiments.

Referring now to FIG. 11, interior accessory panel 170 is secured to main body 12 using a number of threaded fastener assemblies 186, each of which include a bolt 188, a nut 190, and a spacer 192 that is positioned between the bottom cover 16 and interior accessory panel 170 to define a gap 194 therebetween. This gap 194 facilitates attachment of various accessories to interior accessory panel 170 by providing space for semi-rigid or flexible mounting straps of accessories to be clipped to or threaded around and through openings 180. While four pairs of fastener assemblies 186 are shown attaching interior accessory panel 170 to bottom cover 16, more or less fastener assemblies may be used in alternative embodiments.

Fastener assemblies 196 are used to couple interior accessory panel 172 and exterior accessory panel 140 to top cover 14 in a similar manner. As shown in FIG. 11, bolts 198 of fastener assemblies 196 are positioned to through aligned mounting holes in exterior accessory panel 140, top cover 14, and interior accessory panel 172, respectively. A first spacer 206 is positioned between outer accessory panel 140 and top cover 14 to define a gap 208 therebetween and a second spacer 210 is positioned between top cover 14 and interior accessory panel 172 thereby defining a gap 212 therebetween.

A pair of removable mounting clips 214 is provided along one edge of interior accessory panel 170 as shown in FIG. 10. Each clip 214 includes a first clip portion 216 that extends around and engages interior accessory panel 170 and a second clip portion 218 that extends away from first clip portion 216 either in a direction perpendicular to first clip portion 216, as shown in FIG. 10, or directly opposite thereto in an alternative embodiment. Second clip portions 218 are sized to engage the shaft of a hunting arrow. Thus the pair of mounting clips 214 may be used in tandem to secure a hunting arrow within the interior of storage unit 10. It is contemplated that additional pairs of mounting clips may be provided within storage unit 10 to provide additional arrow storage. Additionally, each mounting clip 214 may be configured to include one or more additional clip portion similar to second clip portion 218 such that multiple arrows may be coupled thereto. Mounting clips 214 may be coupled to outer accessory panel 140 in a similar manner.

Referring now to FIG. 10 in combination with FIGS. 12-17 as appropriate, the details of interior accessory panel 172 will be described. In the illustrated embodiment, interior accessory panel 172 includes an upper shelf 220 and a lower shelf 222, which are integrally formed with the main body 224 of interior accessory panel 172. One or more additional shelves 226 (shown in phantom in FIG. 10) may be positioned between shelves 220, 222 by inserting fasteners (not shown) through select openings 184 formed around the outer perimeter of main body 224. In one embodiment, the horizontal portions 228, 230 of shelves 220, 226 are shaped to substantially match the interior geometry of the top cover 14 at desired mounting locations to minimize any gaps between horizontal portions 228, 230 and the adjacent interior surface 166 through which items placed on shelves 220, 226 could fall during transport. However, it is contemplated that shelves 220, 226 may constructed having a generally rectangular shape in alternative embodiments. One or more mounting holes 232 may be formed through the vertical lips 234, 236 of shelves 222, 226 as shown. Additional mounting holes 238 may be formed through interior accessory panel 172 in any number of patterns. Together mounting holes 232 and mounting holes 238 may be used as connection or tether points for bungee cords or other fasteners (not shown) for securing stored items in position on shelves 220, 226.

In an alternative embodiment interior accessory panel 172 is entirely symmetrical across its horizontal axis to allow the storage unit 10 to be reconfigured for right hand or left hand use by simply flipping the orientation of the overall storage unit 10 with respect to the desired mounting location. In such an embodiment, shelves 220, 226 may be reconfigured having a vertical lip that extends both above and beyond respective horizontal portions 228, 230. Alternatively, interior accessory panel 172 may be provided as three separate pieces, a flat vertical portion that includes pattern of openings 180 and that remains fixed to the main body 12 and removable shelves that can be disassembled from the main body portion of interior accessory panel 172, flipped 180 degrees, and reattached to the main body portion to reconfigure the storage unit 10 for either right hand or left hand operation.

As shown in FIG. 12 in particular, the vertical lip 240 of upper shelf 220 has a number of slots 242 formed therein that create a series of upward projecting fingers 244, which may be used to hang various accessories or other components within storage unit 10. One or more c-shaped openings 246, shown in FIG. 16, may also be formed through the horizontal portion 228 of upper shelf 220 for hanging the straps of additional components such as optics, cameras, etc. (not shown). As shown, openings 246 include an arched portion 248 with two inwardly extending ends 250, 252. To secure the strap of a given component within an opening 246, the strap is inserted upward through the arched portion 248 of opening 246 and shifted toward interior surface 254 of top cover 14 until a portion of the strap is positioned at one end 250 of the opening 246 and another portion of the strap is positioned at the opposite end 252 of the opening 246.

In the embodiment illustrated in the drawings upper shelf 220 and/or lower shelf 222 are formed integrally with main body 224 of interior accessory panel 172 and are therefore constructed of the same rigid material as main body 224, which may be aluminum, power coated steel, stainless steel, fiberglass, or a rigid polymer, as non-limiting examples. In alternative embodiments, one or both of shelves 220, 222 may be manufactured separately from main body 224 and coupled to main body 224 using fasteners in a similar manner as illustrated with respect to shelf 226. Alternatively, one or both of shelves 220, 222 may be coupled directly to top cover 14 either removably using fasteners or permanently using an adhesive or other bonding technique.

In an alternative embodiment an insulating material may be provided within all or select sections of main body 12 for use in applications where storage unit 10 is used as a cooler for food or water storage. A polyisocyanurate foam or other insulating material may be embedded within the fiberglass shell of main body 12 or coupled to interior surfaces thereof. In one exemplary and non-limiting example, a cooler compartment (not shown) may be formed toward the top or bottom end of main body 12, with a top surface of the cooler compartment creating a storage shelf for other accessories.

In one embodiment, this ambidextrous operation is achieved by removing mounting hook 108 from the first end 72 of bottom cover 16 and attaching mounting hook 108 at the second end 92 of bottom cover 16 through an opening 258 is formed through the second end 92 of base portion 112. Opening 258 may be left open to allow for drainage of any condensation that forms within storage unit 10 or be closed using an optional plug 260. Alternatively, storage unit 10 may be include two mounting hooks—one permanently positioned at the first end 72 and one permanently positioned at the second end 92. When configured for right-hand operation, second attachment strap 126 engages mounting points 94, 96 to secure the bottom end of storage unit 10 in a vertical configuration.

In the embodiments described herein storage unit 10 is manufactured having a durable construction capable of withstanding extended exposure to weather and rough handling. Thus, main body 12 may be made of a rigid material such as fiberglass, a roto-molded polymer, or metal as non-limiting examples. Exterior grade materials are used for flexible or semi-rigid attachment features of storage unit 10 including, but not limited to, carry handle 18, toggle 38 of latching mechanism 26, gasket 156, attachment straps 124, 126, and the various components of backpack-style carry strap system 74. Hardware components, including the various fasteners described herein, portions of latching mechanisms 26, 28, mounting points 88, 90, 94, 96, and mounting hook 108 may be stainless steel or other weather-resistant material. Accessory panels 140, 170, 172 are made from a power coated steel, anodized aluminum, or other material that provides a rigid construction and weather resistance.

While embodiments of the invention have been disclosed in connection with a tree stand for use when hunting, it will be apparent that the storage unit 10 may be utilized by hunters, sportsman, and outdoor enthusiasts in many alternative applications. As non-limiting examples, storage unit 10 may be positioned at a base camp location or along a trail route and utilized to store first aid supplies and/or as an animal-resistant food or water cache by sportsman or outdoor enthusiasts. Storage unit 10 may also be positioned at or near ground level in a vertical or horizontal orientation or any combination therein within a hunting blind or near a hunting or fishing site for use as a distribution hub for fishing or hunting supplies. Alternatively, storage unit 10 may be secured to a boat, recreational vehicle, Jeep, or other land vehicle and utilized in either a vertical or a horizontal configuration for gear transport and storage. The rugged, secure, and watertight design of storage unit 10 is especially advantageous for the transport and storage of expensive and delicate specialty equipment such as firearms, optics, and photography equipment and may be used to pre-stage or pre-stock a hunting location with food, ammunition, and other supplies in advance of a hunt by the sportsman or a hunting guide, creating nimbleness and stealth for the hunter on the day of the hunt.
